My invention relatesto improvement-s in gas heaters, and it-consists theconstructions, combinations and arrangementsherein described andclaimedf 1 An object of my invention is to provide a' gas heater inwhich the heated'air instead of largely rising as withan ordinary gasheater is" distributed laterally around. V A further object of myinvention is to providea device of the type described hav-v ing meansoperated by the ascending cur-' rent ofhot air f'or causing such lateraldistribution of theheated air current. V

A further object of myinventioniis to provideadevice of thetypedescribed which is simple in construction but positive in action, andwhich does not require any attention for its eflicient operation,

Other objects and advantages will appear in the following specification,and the novel features of the invention will be particularly pointed outinthe appended claims.

My invention is illustrated in the accom plication, in which- Figure 1is a side view-of the device, certain parts being'brokenaway or shown insection, f' 7 Figure 2 is a section along the line 2 2 looking in thedirection of the arrows, and Figures 3 and 4 are enlarged detail viewsof portions of the device.

panying drawings forming part of this ape .ln carrylng out my mvention Iprovide a tapered metal shell 1," open at its bottom and atit-s top. Atthe bottomof the'shell is an exterior ring 2, and to this ring aresecured legs 8., These legs, as .will be ob-' v served, are bentoutwardly and continue upwardly as shown at 3*.- The purpose of theextensions 3*, which are spaced from the shell Lie to afford a holdingmeans for the flexible gas tube 7 YWhen the heater is not in use thisgas tubemay be wound by the plate 4 and it would prevent the,

around the bottom portion of the shell and the coilswill be heldinposition means Below the bottom of the shell is a plate- 4, whichserves as a,

of the extensions 3*.

Sl11l1 as for instance, 'where a burning match is dropped through the,bottom'of2 the heater, inwhich case it would be caught burning of thecarpet or, floor.

At 5 I have shown the valve control of a burner of any suitable type,while within the shell a e the inner b nerip rtionsa source-of gas, asbythe tube '7.

' explained.

The burner may be attached to any At the .top of the shell l isa ring 8'secured upon a rod lO extending. through and beingifastenedto-the-shell 1. Secured suitable I.

and; i below'this ringis a bearing member 9 which,

to the bearingv member 9 is ajrod'll which alsopa'sses through the shell1 being secured thereto by means of nuts 12 on either side of the shelThebearing member 9 has extending upardlyfrom itscenter a bearingpin 13(see Figure 4). Secured topthe ring 8 are L the position of which maybeadjusted by the nuts 18. y

A shaft 19 is provided and to this shaft;

issecured a propeller 20. by means of nuts 21.. The propeller. ispreferably a circular blades being disposed in angular relation with theplane of the disc, as shown in the drawing... Above'the propeller andsecured to'the-shaft 19 are vanes 22. It will be obshaped brackets 14and carried by the brack- ,ets 1s a frame 15, the central porti0n'16 of,

which has an adjustable bearing screw 17,

disc having blades punched therefrom, the I served, that the bottomportions of these vanes are curved forapurpose hereinafter The shaft 19has'areduced extension 23 arranged to enter a recess, 2 1 in the adjusting screw'17. -The lower end of the shaft 19 has a recess 25, a steelball being fixedly V held therein and being arranged to rest on thebearing pin 13 of the bearing 9.

From the foregoing description of the various parts of the. device. theoperation thereof may be readily understood. The legs 3" raise theshelll from the floor so as toprovide 'a'free circulation of airunderneath.

The burner being lighted heats the airwith- 'in' the shell which thenrises and is concentrated by means of the tapering shell. The risingcur'rent'of hot air impinges on the blades of the propeller 20,"thusrotating it.

This rotation is easilyefifected because the shaft 19 upon which theprQpeller is borne I turns on the ball 26, which in turn rests on thepin 13', the upper end of the shaft being held in the recess '24. Theturning of the shaft 19 turns the vanes 22' andthese cause the lateralcurrents of air to be thrown out radially. Thus the heat which wouldotherwise rise is spread out so that anyone in the i in ty wi 'g ttheben fit the eof in. a dition to getting the heat radiated from the shell1.; The device is therefore particular: 13 effic ent in} deliveringheat-where 1t W111 do the most good; that is to say, largely in alateral direction.
